Abstract
A double row, angular contact ball bearing comprises of an integral inner race ring and an integral outer race ring, the outer race ring having at least one circumferential depression between the rows of balls and the inner race ring having a circumferentially radially extending end member axially outside each row of balls. The present invention also relates to a method of manufacturing double row, angular contact ball bearings by shaping sheet metal or tubular work pieces to finished inner or outer race rings by rolling, pressing or deep drawing, introducing rows of balls between the race rings, shaping the race rings to final form by rolling or pressing, and rolling the rows of balls constantly about the circumferential periphery of the inner race ring during the rolling or pressing of the race rings.
